NCT05069246

Brief Summary

A double-blind randomized clinical trial was conducted for 14 days with 37 systemically healthy patients having chronic generalized gingivitis. The current study was designed to investigate the anti-inflammatory and antimicrobial efficacy of Nigella Sativa oil compared with chlorohexidine; assessing clinical parameters and gingival interleukin 6 (IL6) and interleukin 18 (IL18) levels and supra-gingival plaque analysis.

Study Arms (2)

Group 1 / Nigella Sativa oil / NS

EXPERIMENTAL

Group 1- Nigella Sativa (NS) N. sativa oil (Al-Hussan Food Products Factory, Riyadh, Kingdom of Saudi Arabia), which was brought from the local market in Riyadh. Each participant was given a 3 weeks supply of oil, and a sterile plastic 15ml graduated measuring cap. They were asked to measure 5ml of oil into the cap and add 5ml of normal drinking water to this and rinse their mouth for 3mins with this solution and spit it out at the end. This was done morning and evening for 14 days. Group 1: Maintained adequate plaque control levels using mechanical methods + N.sativa oil (5ml oil + 5ml water) pulling for 3 mins twice daily in the morning and at night (after brushing/breakfast in the morning, and after brushing and before sleeping at night). Unified oral hygiene instructions and instructions for each intervention were provided to all participants.

Other: Nigella Sativa oil

Group 2 / Chlorohexidine / CHX

ACTIVE COMPARATOR

Group 2- Chlorohexidine (CHX). Chlorohexidine (Middle East Pharmaceutical Industries Ltd, Riyadh, Kingdom of Saudi Arabia). Each participant was given a 3 week supply of chlorohexidine. They were asked to use 10ml of CHX morning and evening, rinsing their mouth for 3 mins and then spit it out at the end. This was done morning and evening for 14 days. Group2: maintained adequate plaque control levels using mechanical methods + chlorohexidine rinse twice daily 10ml in the morning and at the night (after brushing/breakfast in the morning, and after brushing and before sleeping at night). Unified oral hygiene instructions and instructions for each intervention were provided to all participants.

Drug: Chlorhexidine mouthwash

Interventions

5ml Nigella Sativa oil mixed into 5ml water prior to use and rinsed in the mouth for 3 mins and spitted out, used twice a day; morning and evening.

Group 1 / Nigella Sativa oil / NS

10ml of chlorohexidine mouthwash used for 3mins and spit out, used twice a day; morning and evening.

Group 2 / Chlorohexidine / CHX
